So clearly I'm doing something wrong yet again.
Well no this issue is heat stress, or leaf burn as fans are not blowing on the leaves. 21-22 degrees on my leaves measured with a heat gun.
Been using 850ppm megacrop with some cal/mag, candy and bloom. All their lineup.
I try to ph at 5.8 throughout the whole grow, but my res just climbs to 6.3 within 24hrs. Which I ph down back to 5.8 and it will repeat itself. Is the cause of all this ph?
Second plant to reach to flowering and it's looking to be the same.
@Esrgood4u since you also run coco with autopots what ph do you aim for in veg to flowering.
